Angles TRS and TRV are supplementary, that is,
m∠TRS + m∠TRV = 180°
(25x + 30) + (5x) = 180
(25x + 5x) + 30 = 180
30x = 180 - 30
x = 150/30
x = 5
Angles TRV and WRS are vertical angles, then they are congruent, that is,
m∠TRV = m∠WRS
5x = m∠WRS
5*5 = m∠WRS
25° = m∠WRS
Step-by-step Answer::
"Each month, the balance in the account increases by 0.25%"
means F(n)=F(n-1)*1.0025
"Elaine deposited $50 into a bank account."
means F(0) = 50
So a recursive definition is
F(n) = F(n-1)*1.0025 for n=1,2,3,4... and F(0)=50
Symbols used in the actual answer choices may differ, but with the same principle.
Answer:
x = 0
Step-by-step explanation:
This is a vertical line, in fact the y- axis
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through
All of the x- coordinates on the y- axis are zero, then
x = 0 ← equation of line
Answer:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Exact Form:
x=1+√5 ,1−√5
Answer:
x=-2
y=4
Step-by-step explanation:
find y intercept let x=0
y=2(0)+4
y=4
find x intercept let y=0
0=2x+4
-4=2x
x=-2
